EngineeringFrontend Developer

Keystone Solutions is seeking a Junior Front-End Developer for a consultancy mission at a client site. The client maintains several applications developed in Java and Angular for a governmental organization. The current Angular version (V.15) needs to be urgently migrated to a more recent version (target V.22). The developer will be responsible for ensuring this technical migration, as well as the associated regression testing, which will be developed during the migration based on the modifications made to each application. Special attention will be given to documenting these changes to effectively manage the regression risk following this migration, along with communication to the relevant key users.
